ALBERT E. JOHNSON, 0F BROCKTON, MASSACHUSETTS, ASSIGNOR TO ,UNITED SHOE MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION 01' NEW JERSEY.

MACHINE FOR MAKING INSOLES.

To all whom it may cimcern:

Be it known that I, ALBERT E. JonNsoN, a citizen of the United States, residing at Brockton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Machines for Making Insoles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for forming insoles, and more particularly to machines for forming What are known commercially as economy insoles.

In making economy insoles the blank is treated by slitting'its face to form a channel and by slitting its edge to form a feather, the slitting operations thus producing two independent flaps. These two flaps are then turned up from the channel and the feather and are brought together to form a single, compound lip. Thereafter reinforcing material, such as canvas, may be applied to the insole and to the lip thus formed.

The present invention contemplates an improvement in the formation of insoles of the general character described and relates particularly to the step of bringing the channel and feather flaps together to form a single, compound lip.

Heretofore various attempts have been made to insure the retention of the two up turned flaps in intimate contact, principally by the use of cement applied to the upper surfaces of the flaps, which become their inner surfaces after being upturned. Such a method of procedure isinefiicient, however, as it has been found that with certain grades of stock cement does not insure a permanent contact of the two flaps.

The principal object of this invention is to provide means for permanently securing together the two contiguous channel and edge flaps of an insole- This object of the invention may be attained by upturning the two flaps of an insole of the type described and applying thereto a series of fastening devices acting to bind the flaps together, the devices being of such a nature as to insure permanence of contact between the flaps. A convenient and efficient manner of Specification of Letters Patent.

Application filed May 14, 1908.

Patented Sept.'8, 1914;. Serial No. 432,765.

providing the desired permanence of contact between the two flaps is by employing fastening devices which ma be inserted in the two flaps, for instance, y being passed through said fia s. The fastening devices may be connects together or formed from a continuous material, and in the preferred embodiment of the invention said devices comprise stitches formed from a continuous piece of suitable fastening material, such as Wire or thread. It should be distinctly understood, however, that the" invention is not limited in its scope to the use 'of a continuous fastening material, but includes the use of any fastening device applied to the independent flaps to bind them together in upturned position and thus form a permanent compound lip projecting from the face of the insole.

For convenience, the invention has been shown embodied in the type of channeling machine fully illustrated and described in the U. S. Letters Patent to William C. Meyer, No. 984,773, issued Feb. '24, 1911. In that machine the knives for slitting and channeling the insole are constructed and arranged to act as plows to turn up the flaps as they are formed and hold them in upturned position, and the present invention in its specific embodiment combines with these devices a sewing attachment conveniently mounted and timed as to its operation to stitch the flaps together during the cutting and upturning operations. Preferably the flaps are secured together by means of a single thread stitch, conveniently a chain-stitch, but as it is believed that it is broadly new to upturn and secure together the two flaps of an insole by means of a line of fastenings, the invention is not limited to the use of any particular form of stitch.

Means is provided to sever the thread when the stitching is completed. This means comprises a knife which is in inoperative position while the line of stitches is being formed, but is brought forward into operative position at the completion of the stitching operation. Preferably the operating movement of the knife is controlled by the lowering of the work support to permit removal of the work.

In addition to the objects of the invention above referred to, the invention also consists certain constructions and arran ments of parts as fully set forth hereina ter, the advantages of which will be obvious to those skilled in the art.

To the accomplishment of these objects the invention comprises the features and combinations of parts hereinafter described and particularly pointed out in the a pended claims,

The various features of the invention will be best understood from a description of one embodiment thereof, such, for instance, as illustrated in the accompanying drawings, in which:

Figure 1 is an elevation of the left-hand side of the channeling machine of the patent to William C. Meyer hereinbefore referred to, in which the present improvements are embodied; Fig. 2 is an enlarged detail, in elevation, of the present improvements viewed from the right-hand side of the machine; F ig. 3 is a front elevation of the parts shown in Fig. 2, a portion of said parts. however, being shown in section on.

the dotted line cz, Fig. Figs. 4 and 5 are diagrammatic elevational views similar to Fig. 2, but with the channel knife and presser-foot removed, showing different steps in the formation of a stitch; Fig. 6 is a detail in section on the line y y of Fig. 4, the presser-foot, however, being also illustrated; Fig. 7 is a diagrammatic view with the parts of the stitching mechanism in similarly related positons, as shown in Fig. 4, but viewed from the opposite side of the machine; and Fig. 8 is an enlarged detail in perspective of the needle and its related parts viewed from an inside position.

In the present instance "the invention has been shown as applied to the usual machine for forming a channel and feather on an insole by cutting channel and feather flaps and then upturning said flaps toward each other to form together a single, compound lip. In this type of machine, a channel knife 1 is utilized, which is provided with a horizontal cutting edge, and a plow 2 at its lower end for turning up the channel flap (see Fig. 8). This knife is mounted in an oblique groove in a knife block 3 (Fig. 2) which is supported upon a knife frame 9 projecting forwardly from a vertically movable support or shank 25 extending upwardly through a guideway 26 conveniently formed in the frame of the machine. The shank of the knife 1 extends across the sole and lies in a plane at substantially right angles to the portion of the edge of the sole which is being operated upon. An edge or feather knife 11 (Fig. is'also provided, the shank of which extends longitudinally of the sole and lies in a plane substantially at right angles to the plane of the shank of the channel knife 1. The shank of this knife is arranged obliquely to the face of the sole, and therefore it also acts as a plow to turn up the feather flap in the formation of the insole (see Fig. 8). The edge knife 11 is mounted in an oblique groove in a knife block 12 (Figs. 1 and 3), which knife block in turn is carried on the knife frame J by means of a. tongue-and-groove connection 15 (Fig. 7). The construction and mounting of the knives "is such that at the time the flaps are out they are upturned and are held by the knives in upturned position. Both knives are capable of vertical movement toward and away from the insole in the guideway 26 to accommodate any unevenness in the sole stock, but are held in their lowermost position and in contact with the sole by means of a suitably arranged spring 31 having a lower bearing aguinst a lug projecting from the shank 25 and an upper bearing against a lug projecting from the guideway 26. The sole is supported upon a work table 35 on a stem 36 mounted in a ver tically movable slide 37 on a bracket 38 which, as usual, may be lowered from the knives for insertion and removal of the sole. The table 35 is rotatably mounted on the stem 36 to assist in feeding the work. A positive, step-by-step rotation is imparted to the work table by means of afriction clutch 67 having motion imparted to it by means of suitable connections with a cam groove 75 in a cam disk mounted on the main shaft 51. The work is fed past the knives and across the support or table 35 by a feeding foot (not shownito which is imparted a four-motion feeding movement. Thewertical motion of the feeding foot is obtained from a cam groove in a disk on the shaft 51 which is connected by means of a suitable train of mechanism to the bar on which the feed foot is mounted. The transverse or feeding movement is imparted to the feeding foot by means of an eccentric (not shown) at the forward end of the driving shaft 51 and operably mounted in the supporting bar for the feeding foot. Rotation of the work support slide 37 is prevented by a pin 121 (Fig. 1) passed through a lug 120 in the slide and into the frame.

All of the parts just described may be and preferably are substantially similar to the parts designated by the same numerals in the patent to William C. Meyer hereinbefore referred to. The channel and feather knives are held in working position and are provided with similar adjustments to suit the varying necessities of the work operated on in a manner substantially as shown in ing shaft 51 is rotated by a rope belt from any convenient source of power, passing over a suitable sheave or pulley P.

Referring now to the novel features comprised in this invention, in the embodiment selected l'rr illustrative purposes, a spool or bobbin of thread for use in making a stitch is held in a receptacle 27 (Fig. 1).

sustained by a bracket 28 mounted in the upper portidn of the frame F. The thread from the bobbin is carried through a guide 29 and given a turn around a convenient form of tension truck 30, ournaled at 32in the bracket 29, and is thereaftercarried downwardly and passed through a thread guide 39 (Figs. 4 and 5) on the knife frame 9. The disk 52 isprovided with a second cam groove 40 (Fig. l) which is engaged by a. cam roll 41 mounted upon a lever 42 or free. end of the lever' iti is provided With a boss 49 (Figs. 3 and 7), at the inner side of which is mounted a needle carrier -19 having suitably secured at its lower end a barbed needle 50 of the usual type for mak ing a chain-stitch. The needle 50 is slightly curved, and extends along the arc of a circle having the center of the pivot 47 as a center so that it may act properly upon the work.

The boss 48 at the lower end of the lever 46 is provided with a transversely arranged'groove =16 (Fig.3) into which projectsa supporting lug 53 of a slide 54 adapted to more in a horizontally arranged recess of the knife frame 9. A hole 56 (see Fig. 6) is out in the inner end of the frame 9 to permit a longitudinal movement of the slide 54. A single cap screw 56* (Figs. 3 and 7 acts behind both. the needle carrier 49 and the slide 54 to the lever 46. The slide 5 is provided with a cam opening 57 into which there projects a roll 58 carried by asmall slide 59 (Fig. 6) mounted for vertical movement in a slot 60 in the knife frame 9 and held in position by a cap plate 61 (Figs. 4 and 6).

The feather or edge knife 11 is provided with a transverse opening 62 (Fig. 8) and the needle is arranged just opposite to and is adapted to pass through said opening in forming the stitch. The knife 11 is also provided with a vertically arranged opening 63 which intersects the transverse opening (32. A. groove at the inner side of the knife provides a. recess for the thread. An cvc-endcd looper 64 is carried by the vertical slide 59 and is so arranged as to have l movement in the vertical opening 63 of the knife 11. The thread from the guide 38 passes through the eve of the looper (34. As the needle mores inward it passes through the channel and edge flaps which have been cut and are held upturned by the knives l and 11, and then into the opening 6'2 and past the opening 63. This move ment of the needle carries the slide 51 with it and causes the surface marked (6 of the cam opening 57 to engage the roll 58 of the looper slide 59 and force said roll downward carrying the looper downward with it and into the opening of the knife 11. This by the needle and carried through the flaps to form a loop (see Fig. 8). ()n the backward stroke of the needle the roll 58 of the looper slide is engaged by the surface marked 7) of the cam opening and the looper is again raised to its initial position. carrying the thread out of the path of the needle. The looper slide 59 ismaintained in any position in which it maybe placed by either of the cam surfaces (1 or b by reason of a friction device formed of a small pad or cup (35 (Fig. 6) of metal or other suitable substance placed in a recess iii the slide 59 and held. by' means of a small coiled spring (it). in contact with the cap plate 61.

The outer end of the slide 54 is provided with an ova'lshaped openingfidf. The for ward and rear edges of the opening 54 are adapted. in the movement of the slide 54. to engage a. roll (38 (Figs. 3 and 7) mounted on the lower end of an arm 69 pinned to a stud 70 which is journaled in the. outer end of the knife frame 9. The stud projects from a. second arm 71 (Figs. 3 and 4) provided at its free end with a slot 76. The knife frame 9 is provided With a curved guidevvay 77 (Figs. 4 and 5) extending on thearc of a circle having the fulcrum of the needle operating lever 46 as a center. This gnideway, therefore, is of the same curvature as the needle 50. Mounted for movement in the guideway 77 is a. slide 78 provided at its upper end with a pin 79 which projects into the slot 'i't'v of the arm 71. The inner end of the slide 78 carries a cast-oil 80 having an eye through which the needle 50 passes. The cast-off is also provided With a lip 81 (Figs. 4 and 5) for covering the barb of the needle as is necessary in per forming its function.

The stitching mechanism described makes a. chain-stitch in the usual manner. The needle is moved forward through the work. the looper is moved downward to bring the thread across the needle so that it may be caught by the barb of the needle and carried through the work on the backward stroke to form a. loop, the Work is then fed with the. loop still on the needle, and the needle again forced through the work, seizing the places the thread in position to be engaged thread to form a second loop an.d.pulling it through the first loop, which is then cast oil".

Owing to'the short and rapid reciprocations of the needle and the nature of the work means should be provided to insure a spreading of the loop on the needle as the needle advances so as to insure apassage of the needle therethrough. It will be obvious to those skilled in the art that in sewing around the toe of an insole, where the turning of the work during the feed causes the loop of thread at times to stand in such a position to the line of movement of the needle that there is a. liability of the needle passing outside of the loop instead of through it, a spreading of the loop as the needle advances will provide such an opening that the needle will always pass throughthe loop. To gain this end a bracket 82 (Figs. 4 and 5) is mounted on the knife carrying frame 9 provided with a spring pressed plunger 94 suitably mounted within a socket H3. The position of the plunger is such that it is engaged by the arm 71 of the cast oil slide on the backward stroke of the needle, and at the outer limit of the needle stroke the plunger has been moved so as to place its spring under compression. Thus on the forward stroke of the needle the forward movement of the spring plunger 84 insures a retention of the east olf lip over the needle barb until the loop carried by the needle has been spread sufliciently to insure a passage of the needle therethrough. whatever ,position the loop may assume relative to the needle. The plunger 84 also acts to take up loose play in the parts and to overpome the shock incident to the reciprocation of the needle. Owing to the relation of the parts just described their operation is such that in making a stitch. as the needle passes forward to pierce the work it will first carry the cast off 80 with it for a short distance and will then pass through the cast off which at this time remains stationary. and the cast-off is not further moved until the front edge of .the opening 54 in the slide 54 engages the roll 68 as in Fig. 5. After the roll 68 has been engaged, its arm 69 is moved forward, carrying with it the arm 71 which is engaged by the roll 79 of the castoff slide 78. This causes the cast-off and needle to again move forward together and to so move during the remainder of the forcontacted with the roll 68 of the arm 69, and in, a similar manner as before described, the arm 71 is moved and carries with it the cast-otl' slide 78, thus moving the cast-oif and needle simultaneously from this point during the remainder of the backward stroke.

The operation and timing of the Working parts of the machine are such that the successive stitches are formed during the cutting and upturning operation and are placed immediately adjacent the junction of the forward end of the severed flaps and the insole. Thus a fastener is applied to the upturned. flaps as soon as they are in a position to receive it. This insures speedy work and a large output from. the machine.

Referring new again to Fig. 1, the lug 120 of the Work support slide 37 is embraced by a block 100, which block is pivoted to one arm of a bell crank lever 101 fulcrurned at 102 on the frame F. The other arm of this bell crank is pivoted to a slide 103 guided in horizontal ways 101 on the frame F. To the slide 103 is adjustahly connected :1 thread-cutting knife 105. The construction is such that the knife 105 is in retracted or inoperative position while the work support is raised and the sole is being operated upon. On lowering the work support to remove the sole the hell crank lever 101 is turned in a direction to move the knife forward across the feather knife 11 to sever the thread at the back of said feather knife.

The knives 1 and 11 are provided with means to limit the depth of cut which they make, which means is conveniently in the form of a presser-foot. In the present instance there is provided a single presserfoot for both of the knives, which presserfoot extends adjacent the cutting edges of the knives and bears on the between substance just in front of said cutting edges. In the resent form of the invention the presseroot is carried by a vertically movable bar 90 (Figs. 2 and 6) which is sustained in a guideway of a support 91. The support 91 is mounted, for in-and-ont movement of the presserfoot relatively to the knives, in a guidewav 92 of the shank 25 which supports the knife carrying frame 9. The support 91 is split adjacent the guide for the prcSser-foot bar 90 and the presser-foot bar is held in its guide by means of a clamping screw 93 which draws the split support together. The presser foot bar 90 is adjusted vertically by rotating a screw 94 (Fig. (3) provided with peripheral teeth adapted to engage with a rack 95 on said presser-foot bar. The bearing surface of the presser-foot is formed of a number of small rollers 96 on a stud 97 at the bottom of the bar 90 and exten.ding.transversely across the cutting edges of the knives. Rollers are used, as a convenient anti-friction bearin surface for the presser foot is thus provided, and preferably a number'of rollers are used as a bearing foot so constructed aids the' turning of the sole during its feed through the machine. On turning the sole it is swung channel knife as a fulcrum, and this fulcrum is located at about the center of the presser-foot. Therefore, a series of rolls extending on opposite sides of the fulcrum point will permit a movement of parts of the presser-foot in opposite directions according to the direction of movement of the particular portioii of the sole on which any. one of the series of rolls bears.

Referring now to Fig. 6 it will be seen that the edge or feather knife block 12 is held in the guide 15 of the knife carrying frame 9 by means of a collar screw 13 as in the patent to William C. Meyer referred to. Unlike the machine of said application, however, the knife block is, slotted at the point where the screw 13 passes throu h it ina manner to permitan adjustment of the knife block toward and from the presser foot 96,,

A headed-screw 14 (Figs. 3 and 6) is threaded into the knife carrying frame and the knife block is provided with a groove 16 (shown best by the dotted line in Fig. 7) to be engaged by the head of said screw.

With this construction, by loosening the screw 13 the edge knife block may be adjusted relatively tation of the screw 14. This adjustment is desirable to take up the wear of the knife and thus always-insure a pressure of the presser foot 96 immediately. adjacent the edge of the knife. It has been found in practice that if the pressure from the presser foot is not applied at the point of cutting. the margin of the sole between the edge of the knife and the presser foot will curl up and permit the knife to dig into the feather and sometimes to cut through it completely thus spoiling the insole. The reason for using rolls of small diameter on the presser foot will now be clear. If the rolls are comparatively large it would be impossible to place the edge ofthe knife sufficiently close to the pressure point to revent the curling up of the sole above re erred to.

To sharpen the knife the block 12 is completely removed from the frame 9 and the tongue and groove connection, formed by the headed screw 14 and groove 16, always insures that the knife block is replaced in exactly the same position relatively to its support and adjacent parts as before its removal. The head screw 14 forms an adjustable index which cooperates with the groove 16 for determining the position to be assumed by the knife on replacement and the screw 13 locks the block securely in the position determined by the index.
